Advise me if the above approach/path is suitable for me & let me know doing this certfications will fetch me a job related to DBA domain?Be aware that having an Oracle certification and no Oracle experience doesn't mean that recruiters will be banging on your door trying to hire you. Certifications are an element in getting hired -- they are not a guarantee. I wrote an article a few months ago that discusses the obstacles in getting a job as a DBA with just an OCA certification.

First work for PLSQL developer, Thumb rule is, a good PLSQL developer can be good DBA in future because of two reasons
1. DBA has to help developers in development stages for fine tuning queries and writing SQL statements for minimizing I/OSome have to do this ... others dont. But it is generally help for most DBA's if they can do this.
2. Good PLSQL developer will be GOOD DBA in futureThis doesn't always apply. To take the extreme example a company may have a superb developer who is a complete nutter .... he perhaps may not interact unproductively as a DBA but a good manager may enable him to contribute his development skills without undue problems.
3. DBA has to know all the options in SQL lang, so that he can help developer in futureAgain IMHO not absolutely true for all DBA's. IMHO In a certification exam context most DBA's can get by their day to day jobs by knowing a subset of 1z0-051 topics and having enough sense to locate, find documentation on and use DDL pertaining to managing the database ( even for something they've never come across before). But few, perhaps even those helping developers regularly, need to know ALL 1z0-047 topics (though I would not deny some might need to know SQL beyond the topics of 1z0-047).
ThanksPS: Lasersoft ... it looks like I've really criticised your post heavily ..... but actually really liked your thinking especially for DBA's who spend a lot of time with a group of developers.
